Add support for the 51nb X210

The 51nb X210 is a replacement motherboard for Thinkpad X200/X201 systems,
based on a modern Kabylake CPU. It also ships with no firmware protection,
making it an ideal coreboot target. This port is based on the support for
the Skylake-based Purism Librem 13v3, with the following significant
changes:

* EC firmware is contained within the system SPI flash, and so a blob of
  EC firmware must be injected to a defined location during image build.
  A tool has been provided to do this.
* GPIO layout is different - this is currently just a raw import of the
  GPIO configuration from the vendor firmware
* The system has two DIMMs, so an additional SPD address has been added
* The USB port layout is different
* The EC must be enabled at boot time through SuperIO-style logical device
  configuration
* EC register layout is different, necessitating changes in the ACPI tables
* The HDA pins are different
* The genx_dec config is different
